Sokmen Bey; one of the sons and the successor of the founder of Artuqids, Artuk Bey, strengthened his rule around the region of Ra’s al Gul (Head of the Rose), also as known as Hasankeyf (Kayalar Fortress). He won the hearts and minds of his people by his conception of justice, understanding and indulgence towards a diversity of religions, religious communions and ethnic groups. The pattern of Adel, the traditional symbol of Artuqids that represents peace, justice and clemency is now in Luna Merdin.
